In the drawingswherein for the purpose of illustration is shown but the preferred embodiment of this invention the letter A may generally designate the entire inven t on which may embody a frame and hood construction B; burner construction C novel boiler and tubing construction 1); and indi cator or gauge means E.

The frame and hoodconstr'uctionB will of course vary in accordance with the use for which the boiler construction Disto be put. Asthe boiler and tubing construction is prioi this specification, and wherein simi- FFi cE marily designed for use in 'connectionfwith I e the generation of steam for vehicle propulsion, the frame and hood construct on B may include front and rear walls 10 and 11 respectively which may be connected in a clients. A "top wall 13 may be providfed which may include sections 1& and'15 hingedly connected, as at '16, at the center of the improved construction A; sidewalls 17 being hingedly connected, as at 18,"to the top. wallsections 14 and 15,,much' in: the same cial construction- A special construction could be that of providing each wall of 'a pair of spaeed'metal plates withasbestos or analogous insulating material therebetween.

provides a compartment 20 adapted to'house the burnerand boiler constructions C; and

D respectively, and insure easy. access there? connected side to by reason of the hingedly and top wallsections. i v e H Referring to the burner construction C, the same includes a substantiallyrectangular shaped casing or pan 25, which may be car The hood construction, however, primarily I ried in any approved manner upon the sup-f portorvehicle chassis to which the hood construction B is attached. The pan is, ofeourse, mounted below the hood construe:

tion B, and provides a pocketvor 'compart-l inent 26 open' to'tlie compartment. or cha n.- ber of thehood construction-B; Hooks 28F analogous to ordinary automotive vehiclehood hooks are provided about the sides and; at the front and rear of the pan 25, as

means of connecting the hood walls to the' pan 25, and vice versa The burner construction furthermore i115: I

cludes a plurality oi longitudinally arranged tubes 28, 29, '30, .81, 32,33 and. 34in;paralle1 relation within thei'pocket or compartment;

26 of the pan 25.;said tubes being arranged" transversely otthe hood B, or rather 'ezg tending parallel witlr the front and'rear walls of said hood construction, substantially as is illustrated in the draw ngs. 1 The burner tube 34Eis centrally disposed, with three of the remaining tubes on each "side thereof;

this tube being known as; the pilot. burner tube,

110 and as will bev subsequently set; forth/ Thistube has oneendtliereot flattened,

as have also the burner tubes 30 and 33 on I "each side thereof. The tubes 30, 33 and 34 are all of the same lengths, and their other end's'areopen and provided with beveled edges 37, substantially as is illustrated in,

Figures 2 and 3 of the drawings and into which ends fuel is fed as will be subsequent- 1y described. The tubes 28 and 29 at the outer side, of the tube 30, and the remainin two tubes 31 and 32 at the outside of the mie 33 each have both ends thereof flattened a and closed. The closed ends of all of the tubes are bolted or otherwise secured I to brackets 39 provided in the burner box or pan 25, substantially as is illustrated in the drawings; The intermediate tubes 33 and 34 are longer than theremaining tubes, and

at their 0 en ends extend through a wall" 39? offthe urner box 25; Each of'the tubes 29 to 34 inclusive are transversely slotted with a series of; slots in the top thereof, throughout their length within the burner b02 25, and through which fuel emits to perunit the properignition thereof.

,Fuel supply'means 40 is provided in connection with the burner construction C,

l which includes a pilot fuel'tube 41 disposed tube 34, and theconstruction of which nozzle will be subsequently tion of the fuel feed fuel to the open end of the directly over-the pilot burner tube 34 and {leading through thewalls 38 and 39 of the burner pm 25, having a nozzle 43 down turned into the open end of the pilotburner described. Thatpor-- means usedto supply 8 tube 33 includes a length of tubing 44 which extends 1 over the burner tube-32 for the length thereof,

and adjacent the side wall 39 ofthe burner sun 25 is bent and returned in a length .45

.the opposite side wall 38 of the burner pan irctly over the burner'tube 33. Adjacent 25 the tubing is bent and extends fora length 46 over the central tube 34, substantially as is illustrated in Figure 5, and extends through the wall 39" of the burner box or pan 25,, having a nozzle 47 thereon which ,jfsupplies fuel to the open end ofth'e burner through the side wall 38 of-the burner; box and is conn'ected'to a transverse length of piping 48-whieh has communication theretube 33; *The tube length 44' has an exit with and which leads into the burner. box 25, having. a length 49 thereof which extends longitudinally over the burner tube 2 9,.and adjacent the wall 39 is bentin a return length 50v overthe burner tube 30. The length 50 adjacent the wall 38 of the burner box 25 a andcwhile still within the compartment .of said burner box is bent to extend. for a length 51 over the burner tube 34, substantially as is illustrated in Figure 5 of the drawings, at its free end extending through the burner box wall 39 and having a nozzle-construction 5 2 thereon to supply fuel to the open end of the burner tube 30.

The fuel torbe used is oil, which enters at 55 into the lengths of tubing having the nozzles 47 and'52 thereon. This oil is conveyed backward and forward longitudinally above, the burner tubes so that the oil will be preheated to a'vaporized. condition priorto its spray into the open ends of the burner tubes-3Q and 33. The burner tube 34 and it individual fuel supply tube 41 are pro}v vided as a means of providing apilotflame for the burner constructionlC. The tubes 28, 29, 30, 31, 32 and 33 are in intercom-c fmunicating relation by means of transverse tubular connections 56, substantially as is illustrated in Figure 5 and the cross sectional view of Figure 8. The tubular con-V V nectlons 56 which extend to communicatethe burner tubes 30 and 33 extend transversely through the central or pilot burner tube 34 in noncommunicating relation therewith. Itca n thus be seen that the vapor fuel will be fed in equal pressure within all of the,

burner tubes exceptthe central pilot burner tube 34, which receives. an independent supply of vapor fuel from the tube or conduit 41and its nozzle 43. I

,The'constru'ction of the nozzles 43, 47 and 52-are identical. Each ofthesame'includes a right angled connection 57 fitted at the end of theburnertube, providinga depending screw threaded tubular stem '58 havingv a Y The boiler and tubing construction'D is of course located within the hood compartment 20 and immediately over the burner tubes v The arrangcment D, in

above described. the main, includes a plurality of tubular headers 60, 61, 62, and 63 arranged in a vertical plane, oneover the other, theheaderGO Jclamping nut 59 adjustable thereon. A piece of copper or analogous pliable tubing being the lowermost and longest, while the header 63 is uppermost" and of the same; length ast-he intermediate-headers 61 and 62. 'All of the headers are arranged on hori- I zont-al axes. .The lowermost header 60 ex tends transversely throughthe side walls -17 of the hood construction B, and at its ends rests upon suitable'brackets 65 which may be appropriately welded to the burnerpan construction 25 or to other frame construction, to support the lower header 60 in a secure relation. The headers 60, 61,62 and 63 are in intercommunicating relation, at each end thereof, as by meansof detachable couplings or union connections 66,

which extends outwardly of the hood' construction B, substantially as is illustrated in Figure 2 of the drawings. Each end wall of eachof the headers i preferably provided With a detachable plug 72 therein whereby access may be had to the interior of the headers for cleaning purposes. The headers are arranged in parallel relation with the burner-tubes, in a plane centrally arranged over the pilot burner tube 3 1; the headers being of considerable capacity, and extending to the extreme top ot'the compartment 20 defined by the hood construction;

A pie-heating arrangement is provided in connection with the boiler construction which includes a pair of spirally wound coils 75 and 76, each wound in a'plane and'fdis posed, at opposite sides of the headers in close proximity thereto. The tube 75 provides aninlet 77 through which water is fed and which flows spirally about the convolutions of the coil 75 toward the center, I thereof, becoming preheated. At its center the coil 75 is outturned, as at 78, at right tion with thepassageway 96 extending angles to the plane of the coil 75, and is connected by a detachable union coupling 79 to the centrally ofiset end. 80 of the other coil 76. The water 'flows across this con-' nection into the coil 7 6 and from the center thereof about its c'onvolutions to the outer convolution thereof, the outer convolution thereof being connected by a detachable coupling 81 to the side of the lowermost boiler header 60; the preheated water thus entering the compartment of the lower header 60 first and being subjectedto heating therein. The level of the water is, of course, such as to fill the intermediate headers 61 and 62; the upper header 63 being utilized as a steam dome.

' A series of spiral coils 82 are provided at the outerside of each of the preheating coils 75, and. 7G, in interlneshing relation, at their upper ends each havng a connection. as by detachable union joints'83, with the header 63. At their lowerends each of the coils 82 has a detachable connection, as by a union joint 84-, with the lowermost header 60. These coils 82 may be of any approved numheader 63 with the lowermost header 60.

These coils are mainly steam generating coils in that the flames of the burner play thereabout. It can thus be seen that all steam vfrom the headers and from the coils heretofore described passes into the uppermost header 63. Abovethe header 63, and in a horizontalplane, a spirally wound coil 88 is positioned, which at its-center has a. laterally extending offset for detachable connection, asby a union 89,'to the top Wall of the upper most header 63, and adapted to receive] steamfrom the uppermost header, 63'to be'superheated asit passes around the various c0'n volutions of the coil 88. Thesuper-heated steam passes ofi" through an outlet tubing 90to a desired location where it may aid in the propulsion ofthe machinery desired. Referring to the indicating means E, a vertically disposed length-of pipe or tubing 92' is placed exteriorly of the hood or casing construction for the boiler arrangement, at

.its upper. end" having communication with the superheated s'teamoutlet90, and at its I lower end having connection with the water compartment of "the"lowermost header 60.

The water in the various headers of the bo ler arrangement of course should rise to a level below which thesame shouldnotfall. This same level of water will, of course,

lower coupling' s' 94 and 95 respectively are secured to thevertical pipe length 92;;at predetermined elevations 1thBI60I1; said couplings-94E- and 95 being's'o connected on the pipelength 92 as n'ot' tol have communicaoccur in" the vertical pipe 92. UDP and through the piping 92, but" being soldered or otherwise connected 'by'end plates 98 to the tubing 92 as to provide anenclosed compart mnt 99 circumferentially about the pipe 92. Gauge tube-s 100 and 101 are respectively con nected to the couplings 94 and 95, by ap proved means 102, as t-olhave communication.

with the enclosedcompartments 99 of said couplings. Appropriatepressure gauges-104 These tubes, l

undesired'level', below the points on the pipe 92 onwhich the. coupling9t is placed. This low eringjof the level of 'water will permit the super-heated steam 'to pass into that portion of the pipe 92 about which the c'ou-- pling 94 is placed, which considerably raises thetem'perature of the oil or other expansi ble liquid within the'comp'artment 99,"tend-V i ng to ex'pand'the same and to indicate upon the gauge 104 that the water level has fallen need of water; the gau 'e 105 operating on the same principle as the gauge 104. The

' .0011 lin s 94-and 95 may be exteriorly covwire mesh in close fitting relation thereon as a means for quick air cooling of the same. A conduit 107 may be connected in the vertical pipe 92 between the couplings '94and 95,"which may have an ordinary automatically operated expansion water 7 feed regulator thereon to maintain the water in the boiler at a desired level. i

-;At the front of the hood construction B an exhaustmanifold or outlet 110 may be positioned, which may be of flaringformation, having a connect on with the compartment 20. of the hood construction at the top thereof, to permit the waste roducts of-oombustion topass therethroug The flame of the burner arrangement, as to intensity, may be regulated by an of the automatic regulators now found on t e market.

From the foregoing description of 'this-in-r Mention it is. apparent that a boiler has been provided, the parts of which arecooperatimely-and compactly arranged as to permit the effective generation ofv super-cheated,

steam. -The coils and headers are so arranged that the steam. generation may take placein as small a place as possible; the water to be turned into steam being exposed overt relatively great surface area incident to the novel arrangement of coils and headersabove the burner arrangement. An importantfeature of the'im roved boiler construction: is that the individual units thereof are. relatively] detachable and accessible. The gauges 104 and 105, in the instance Where the boiler is used for automotive vehicle propulsion may be placed upon a. dash or other suitable location,

vVarious;changesin the shape, size, and

arrangement of parts .may be made. to the form of invention herein shown. and described, without departing from. the spirit of the invention or scope. ofv thc claims.
